Abstract

L’invention concerne un appareil de traitement d’eau pour pile à combustible, dans lequel l’eau récupérée d’une pile à combustible est traitée au moyen d’une unité de désionisation électrique, qui est amélioré de manière à assurer une défluoration satisfaisante de l’eau s’écoulant dans l’unité de désionisation électrique. L’eau résiduaire provenant d’une chambre d’électrode négative d’une unité de désionisation électrique (4) est introduite, par un tuyau de transfert (18), dans une chambre de lavage à l’air (20) dans laquelle un lavage à l’air est effectué. L’eau obtenue est décarboxylée dans une chambre de décarboxylation (30), et est amenée, au moyen d’une pompe (62), à s’écouler successivement à travers des chambres de défluorination (70,72,74) et des chambres de démétalllisation (80,82) avant d’être introduite dans l’unité de désionisation électrique (4).
